[Rdo-list] OS Liberty + Ceph Hammer: Block Device Mapping is Invalid.

Wednesday, 9 December 2015

Can someone help me?
Help would be highly appreciated ;-)

Last message on OpenStack mailing list:

Dear OpenStack-users,

I just installed my first multi-node OS-setup with Ceph as my storage backend.
After configuring cinder, nova and glance as described in the Ceph-HowTo
(http://docs.ceph.com/docs/master/rbd/rbd-openstack/), there remains one blocker for me:

When creating a new instance based on a bootable glance image (same ceph cluster), it
fails with:

Dashboard:

Glance seems to work well. I was able to upload images.
Creating non-bootable disks seem to work, as soon as I try to make one bootable, it
fails.

This seems to be related to the known threads I found online but the mentioned fix was
merged long before Liberty so I am finaly stuck at this point.

How can I fix this problem?

Thanks.

Kind regards
Kevin
